I bought this watch couple of years ago... as i am keen with the slider ruler at the bezel. However to this date, i have never actually use it. Too many thing to memorize for it to be effective... nonetheless it is kindda cool (well the truth it is not super complicated to use but im just plain lazy to read the long instruction)
Basically a slider ruler is an old school calculator made before things goes digital. It is useful to count multiplication and conversion. I have never truly explore the full use of it , but perhaps I would....
Anyone tried it before...feel free to share...
